inactive. Among dppe analogues, replacement of phenyl groups with ethyl or benzyl groups resulted in inactivity for both ligands and the corresponding gold complexes whereas substitution with cyclohexyl or heterocyclic ring systems yielded ligands and/or gold complexes with antitumor activity. Among substituted-phenyl dppe and dppe(AuCl)2 analogues, 3-fluoro, 4-fluoro, perdeuterio, 4-methylthio, and 2-methylthio
描述了与双(二苯基膦基)乙烷(dppe)有关的双膦及其金配合物,在多种可移植肿瘤模型中具有活性。在第1-5天以最大耐受剂量(MTD)40μmol/ kg腹膜内给药时,dppe可重复产生ip P388白血病小鼠的寿命(ILS)100%。氯金(I)与dppe中的每种膦配位得到的复合物具有相似的活性,但剂量水平比dppe低得多。金(I)配合物的MTD为7μmol/ kg。在dppe的其他金属络合物中,Au(III)络合物具有活性(大于50%ILS),而Ag(I),Ni(II),Pt(II),Pd(II)和Rh(I)络合物具有活性。不活跃。在dppe类似物中,用乙基或苄基取代苯基会导致配体和相应的金络合物均失活,而用环己基或杂环系统取代会产生具有抗肿瘤活性的配体和/或金络合物。在取代的苯基dppe和dppe(AuCl)2类似物中,3-氟,4-氟,氘代,4-甲硫基和2-甲硫基类似物是有活性的。4-甲
